Security Apparatus and Control Method Thereof

2. The security device of claim 1, wherein the context-aware cryptographic process comprises an ID-based cryptographic process in which the ID includes the recorded context information.

3. The security device of claim 1, wherein the context information intake device comprises at least one of a camera, a laser scanner, a radar, and a sonar.

4. The security device of claim 1, wherein the context information comprises a recorded image.

5. The security device of claim 4, further comprising a communication unit, wherein the controller is further configured to cause the communication unit to transmit the recorded image to an external server or device when the recorded image does not include any pre-recognized object.

6. The security device of claim 1, wherein the context information comprises at least one of distance and direction information between the security device and the object, Global Positioning System (GPS) information of the security device, GPS information of the object, environment information within a preset range from the object, or temperature or radioactivity information within a preset range from the object.

8. The security device of claim 1, wherein the context information is classified as public or private.

9. The security device of claim 1, wherein at least a portion of the context information is obtained using the sensor of the security device.

11. The method of claim 10, wherein the context-aware cryptographic process comprises an ID-based cryptographic process in which the ID includes the recorded context information.

12. The method of claim 10, wherein the context information intake device comprises at least one of a camera, a laser scanner, a radar, and a sonar.

13. The method of claim 10, wherein the context information comprises a recorded image.

14. The method of claim 13, further comprising transmitting the recorded image to an external server or device when the recorded image does not include any pre-recognized object.

15. The method of claim 10, wherein the context-aware cryptographic process comprises comparing a Message Authenticated code (MAC) value associated with the object with a pre-calculated value.

16. The method of claim 10, wherein the context information comprises at least one of distance and direction information between the security device and the object, Global Positioning System (GPS) information of the security device, GPS information of the object, environment information within a preset range from the object, or temperature or radioactivity information within a preset range from the object.

18. The method of claim 10, wherein the context information is classified as public or private.
